The concrete has been designed using high-density natural aggregates and steel reinforcing fibers, according to structural concrete requirements. The damage caused by high temperatures to concrete has been analyzed by residual physical, mechanical and microstructural characterization after thermal shock exposure. The analysis of the results allows us to determine the behavior and verify the integrity of the shielding concrete over the different temperature ranges.}, organization = {This research was co-financed by the European Regional Development Fund and the Ministry of Economy, Industry and Competitiveness within the framework of the project RTC-2016-5637-3 and in collaboration with the company INGECID and the LADICIM of the Universidad de Cantabria.}, publisher = {Elsevier}, publisher = {Cement and Concrete Composites Volume 103, October 2019, Pages 80-88}, title = {Effect of elevated temperature on the mechanical properties and microstructure of heavy-weight magnetite concrete with steel fibers}, author = {Thomas García, Carlos and Rico Arenal, Jokin and Tamayo Castañeda, Pablo and Ballester, Francisco and Setién Marquínez, Jesús and Polanco Madrazo, Juan Antonio}, }
